BACKGROUND OF THE INVENTION 1 Field of the Invention

The present invention generally relates to the field of cleaning partsand, more specifically, to a method of cleaning and/or sanitizingjewelry and other small parts.

2. Description of the Prior Art

Precious stone and metal jewelry is at its most beautiful when perfectlyclean and free from body oils, film, grime, and other deposits that canhide the shine, sparkle and character of the jewelry. Notwithstandingthe desirability of maintaining jewelry in a very clean state, it isdifficult to effectively clean jewelry.

The professional process of cleaning jewelry involves the followingsteps. First, the jewelry pieces are boiled in a concentrated cleaningsolution for about 15 to 30 minutes. Next, the jewelry is removed fromthe concentrated cleaning solution and is rinsed with hot water. Lastly,the jewelry is subjected to high pressure steaming to quickly remove anyremaining water to prevent spotting. While cleaning in this mannerrenders a piece of jewelry the benchmark 100% clean, the equipment,time, and steps involved in professionally cleaning jewelry is out ofreach of the vast majority of consumers and even small jewelry storeswith limited space. As a result, there have been attempts to devise lesscostly and involved devices and methods for cleaning jewelry. Forexample, liquid jewelry soaking solutions are available. A user willsoak a jewelry piece for some time, and then attempt to brush away thegrime. Results of about 30-50% are about the best achievable. Commercialultrasonic jewelry cleaning machines are now being sold. However, thesemachines can only accomplish cleaning to about 70-80% clean. Also, mostof these machines are bulky, heavy and costly. See U.S. PatentPublication Nos. 2013/0306111 to Myers; 2004/0040586 to Kumar and2010/0186780 to Larocca et al for a dental appliance cleaning apparatus.See also, U.S. Pat. No. 9,339,852 to Campbell that discloses a cleaningdevice used to clean jewelry by heating clean water dispensed throughjet nozzles to spray the jewelry while in a rotating basket.

U.S. Pat. No. 4,941,490 to Gross discloses a low temperature apparatusfor cleaning jewelry. The Gross device delivers a low temperature mistof cleaning liquid and a stream of compressed warm air for drying thejewelry once it is cleaned.

U.S. Pat. No. 5,209,784 to Bellman discloses a method and apparatus forjewelry and small parts cleaning. In the Bellman method and apparatus, alarge mesh basket with internal hooks posts and compartments is providedfor placement in an automatic dishwasher, where the water and waterlaced detergent will be allowed to impinge on the jewelry piecescontained in the basket and thereby cause cleaning. According toBellman, results of 80-85% cleaning of oil and dirt can be achievedusing the patented method. While this range of results is comparable orbetter than that achieved with other available non-professional cleaningmethods, it still falls short of the perfect results achieved byprofessional methods of cleaning, which leaves jewelry most brilliant.

Accordingly, there remains a need for a simple and easy to use methodand kit for cleaning and/or sanitizing jewelry which achieves 95%+cleaning results.

Known jewelry cleaning devices use sonic technologies, pressurized steamand other cleaning chemicals to remove or dissolve foreign substancesfrom jewelry. These devices are largely for personal use.

More recent jewelry cleaning devices and methods are sonic cleaners,described in U.S. Pat. No. 6,719,850 issued to Glucksman et al. on Apr.13, 2004, and U.S. Pat. No. 7,448,398 issued to Glucksman et al. on Nov.11, 2008; steam cleaners, described in U.S. Pat. No. 6,129,097 issued toEdward Papandrea on Oct. 10, 2000 and U.S. Pat. No. 7,257,319 issued toMichael Clarke on Aug. 14, 2007; and a method describing a completeimmersion in cleaning solution, without vibration, described in U.S.Pat. No. 6,076,538 issued to Jon Frankson on Jun. 20, 2000 and patentsby others almost a half-century before that time.

U.S. Pat. No. 6,719,850 discloses a small, quiet, sonic cleaner wherejewelry is immersed in a cleaning solution and vibrated in the sonicrange. The patent also discloses the method for using the cleaner. Thepatent discloses hooks within the cleaning tank where jewelry can befastened which rotate in response to the vibrations. U.S. Pat. No.7,448,398 discloses an improvement over U.S. Pat. No. 6,719,850 in thatit provides for removable tanks for ease of disposal and replacement ofspent cleaning solutions. Both of these patents disclose machines thatare primarily for in-home use.

U.S. Pat. No. 6,338,350 discloses a device which can be attached to asteam cleaning machine to clean jewelry. The device consists of a nozzlethrough which a jet of steam enters a closed mesh container that holdsthe jewelry being cleaned. The attachment is mounted to the steamcleaning machine through a support located at the open top of the neckportion of the attachment. This patent also teaches the use of tweezersthrough an opening in the mesh container which can be manipulated by theuser to target the jet of steam onto the jewelry being cleaned.

U.S. Pat. No. 7,257,319 discloses a portable jewelry cleaning devicethat emits steam through a tube over the jewelry being cleaned. Acontainment device is optionally provided which catches any jewelrywhich is dislodged during cleaning. Unlike the disclosure in U.S. Pat.No. 6,338,350, this device houses a steam generator and is selfcontained. A water reservoir is also housed within the device which isfilled by the user.

U.S. Pat. No. 6,076,538 discloses a jewelry cleaning kit and methodwherein the user secures the jewelry in holding basket and dunks thebasket with the jewelry into a cleaning solution. The basket with thejewelry is then placed in an automatic dishwasher for a final cleaningwith a water spray and steam.

It has also been proposed to heat cleaning fluids, including water andcleaning solutions, by heating the same in a microwave oven. In U.S.Pat. No. 9,365,809 to Maiuri Cleaning Solution for Smoking Paraphernaliaand Method are disclosed in which identified cleaning solutions, aloneor diluted with water, are heated prior to being applied to a soiledsurface for cleaning. The patent teaches placing the cleaning fluids orsolutions in a microwave oven for different time periods to cleandifferent tarnished surfaces, suggesting that the most effectivetemperature is approximately 180° F. The solution is then sprayed onto asoiled surface to be cleaned. It is suggested that different heatingtimes ranging from 10-120 seconds in the microwave set on “high” fordifferent solutions may be required to clean different levels of grimeor soil surfaces using temperatures ranging from 120°-182° F. U.S.Patent 2005/0159326 to Holyworth discloses a Method for Cleaning Carpetsand Other Surfaces by using a vessel containing a cleaning compositionplaced into a microwave oven and heated to a temperature ofapproximately 90-220° F. after which the heated cleaning composition isapplied onto the soiled surface by a means of a spray dispenser.

In U.S. Pat. No. 2,141,713 to Hensler et al a machine is disclosed forcleaning jewelry that uses a mounting panel for supporting the machineon a vertical surface, such as a wall, including a motor secured to thepanel. A vertical shaft of which extends downwardly to supporting abasket into which items to be cleaned may be placed. A non-heatedcleaning solution is placed in a liquid non-circular shaped containerand the basket is submerged in the cleaning solution, after thecontainer is secured to the panel, so that the basket is positioned “offcenter” to produce a rotation of the cleaning solution to physicallyimpinge against the items to be cleaned. This machine is not portableand cannot be used to sanitize the items to be cleaned. Furthermore,using a motor to rotate the basket requires access to an electricaloutlet or hardwired connection to a source of electricity.

In U.S. Pat. No. 5,876,513 to Frankson a holding basket receives itemsto be cleaned. The basket is placed into a cleaning solution to coat thejewelry with the solution after which the basket with the items areplaced into a dishwasher and run through wash and dry cycles thatremoves the cleaning solution and grime from the items in the basket.This solution requires a dishwasher, is clearly not portable and theeffectiveness of cleaning will be a function of the temperature of thehot water supply delivered to the dishwasher. The mentioned temperaturesof tap water heated to “below 120° F.” would not be adequate to sanitizethe jewelry by the proposed method.

DETAILED DESCRIPTION

Referring now specifically to the figures, in which identical or similarparts are designated by the same reference numerals throughout, andfirst referring to FIG. 1 a first major component of the cleaning devicein accordance with the invention includes a generally cylindricalcontainer 10 for receiving a fluid in a jar or tub 12. The containeralso includes a lid 14 that can be threadedly attached to the jar bymeans of conventional threads or other means. The details of the jar 12and lid 14 will be described in more detail below. Besides thecylindrical container 10 another major component of the cleaning deviceis a spinning mechanism or carousel receivable within the jar 12, as tobe described.

Referring to FIG. 1-1C the jar or tub 12 includes a generallycylindrical inner shell 12 a. An outer shell 12 b encloses the innershell 12 a. The axial height of the inner shell corresponds to theheight of the outer shell of the inner shell but includes an annular orcylindrical extension forming a threaded region. A circumferential grove12 c is provided on the exterior surface of the inner shell 12 a. Theupper edge of the outer shell 12 b is provided with an inwardly directedannular rim or lip 12 d preferably tapered to facilitate the rim to besnapped into the annular groove 12 c to retain the two walled members inplace once assembled. An outer thread 12 e formed on the inner shell 12a extension is conventional and configured to mesh with an inner thread14 a (FIG. 1I) within the lid or cover 14. Preferably an inner marking12 f is provided as shown in FIG. 1A to designate a maximum fill linefor filling of a fluid such as water, a cleaning solution or a mixturethereof. As shown in FIG. 1A, the inner and outer shells 12 a, 12 b areconfigured to provide an inner space 12 g between the shells whenassembled to provide thermal insulation to maintain the temperature ofthe outer shell 12 b comfortable to the touch when gripping thecontainer during use as to be described. As shown in FIGS. 1A and 1D thejar 12 has a bottom wall and a top opening at opposing axial ends alongthe container axis A_(c). Provided on the bottom wall is a centralraised portion 12 h with a central depression 12 i, that is shown inFIG. 1D. Provided around the central raised portion 12 h are integrallymolded spaced upwardly projecting tabs or protuberances (FIGS. 1A and1D) that will be further described in connection with FIG. 9I. Holes 12j (FIGS. 1A and 1F) are formed in the bottom wall of the outer shell toallow any water as other fluid trapped between the inner and outer walls12 a, 12 b to escape as well to prevent buildup of pressure between thewalls when water or other fluid is heated in a microwave oven and turnedinto steam.

The cleaning device in accordance with the invention can be used withany fluids and cleaning solutions, with different degrees of advantage,at sanitizing and below sanitizing temperatures. However, best resultsand sanitation of the items to be cleaned are best obtained when thefluid or cleaning solution is heated to a temperature of at least 170°F. and preferably in excess of 170° F. Towards that end the inner andouter shells 12 a, 12 b may be formed of any suitable microwavablematerials that can withstand these temperatures. Preferably, the innerand outer shells are formed of a plastic material, such as but notlimited to a high temperature polypropylene. The inner and outer shellsneed to withstand the indicated temperatures without deformation orwarping. Preferably, the thickness of the shells, the size of theinsulating air gap or space 12 g are selected to render the outer shellcomfortable to the touch even when the temperature of the fluid withinthe inner shell is heated to sanitizing temperatures. Preferably, theouter shell is provided with a series of circumferential or elongateddepressions 12 k as shown in FIGS. 1A-1C to receive a user's fingers toprovide reliable gripping of the container and prevent slipping thereofwhen removed from a microwave oven. Slip resistant feet 12L (FIGS. 1aand 1F) are provided at the bottom of the jar or tub 12 to preventsliding movements when the cleaning is operated as described withreference to FIGS. 9A to 9X.

Referring to FIGS. 1H and 1I, the lid 14 is provided with inwardlyprojecting santoprene tabs 14 b that serve as rests for the carousel asto be described. Rubber slip-resistant lands 14 c are provided on theother side of the lid when it serves as a base for the carousel on acountertop or other surface.

Referring to FIGS. 2-2B, a carousel or spinning mechanism 16 is a secondmajor component of the cleaning device and includes a basket forming anannular tray 18 for supporting small items to be cleaned and dimensionedto be removably received within the jar 12, the basket defining a basketaxis A_(b) that is substantially coextensive with the container axisA_(c) when the basket 18 is received within the jar 12. The basket 18diameter is somewhat smaller than the inner diameter of the inner shell12 a to maximize the size of the basket while providing a clearance withthe inner surface of the inner shell to allow the basket 18 to rotatefreely about the axes A_(c), A_(b) without contacting the inner shell.The basket 18 includes a lower transverse base 18 a and a generallycylindrical circumferential wall 18 b. Projecting upwardly, as viewed inFIG. 2, from the base 18 a are circumferentially spaced upwardlydirected projections 18 c and downwardly projecting generally radialcircumferentially spaced fins 18 d.

The base 18 a is joined with an upwardly projecting central post or mainbody 20, preferably integrally formed with the base 18 a at the lowerend thereof as shown. An annular recess 22 is provided in the regionwhere the central post 20 meets the base 18 a. At the upper end of thecentral post or body 20, as viewed in FIG. 2, the upper free end isformed with a downwardly projecting tubular or annular extension 24 andan upwardly extending tubular or annular portion 26. The tubularextension 24 has an internal diameter d₁ and the tubular extension 26has an inner diameter d₂ where d₂ is shown to be greater than d₁. Thetubular extension 24 is dimensioned to receive a spiral plunger 27 withclearance to allow the plunger to move axially up and down through thetubular extension while maintaining its central position along the axisA_(b). Provided along an upper edge of the annular or tubular extension26 there are provided at least two sloping or inclined cam surfaces 20 a(FIG. 2G) symmetrically arranged in relation to the axis A_(b) tocooperate with a spin clutch 28 and having stop surfaces 20 b so thatthe clutch can slide along the inclined surfaces 20 a and be stopped bythe stop surfaces 20 b. The spin clutch 28 is provided with an annularrim 28 a that has a diameter greater than d₂ and a number of outwardlyprojecting radial tabs 28 b, equal to the number of cam surfaces 20 aand stop surfaces 20 b. The clutch 28 is provided with a centralrectangular slot 30 (FIG. 2F) having a length and width dimensioned toreceive the rectangular cross-section of the spiral plunger 27 withsmall clearance to allow the plunger to freely move upwardly anddownwardly through the rectangular slot 30 with minimal friction. Acup-shaped clutch cap 32 is fixed to the outer surface of the tubularextension 26 as shown to provide sufficient axial clearance “h” (FIG. 2)to allow the spin clutch 28 to move up and down in response to verticalmovements of the plunger 27 to disengage the tabs 28 b from the camsurfaces 20 a (FIG. 3B) when the clutch is raised to bring the rim 28 ainto contact with the cap 32 and engage the tabs with the cam surfaceswhen the clutch is lowered to bring the rim 28 a into contact with theportion 26 of the post 20. When the spiral plunger is pushed downwardlyto urge the radial or lateral projections or tabs 28 b to slide on thecam surfaces 20 a into engagement with the stop surfaces 20 b to therebyengage and rotate the clutch and, therefore, likewise cause the centralpost or main body 20 to rotate when the spiral plunger is forceddownwardly. When the spiral plunger 27 has reached its lower mostposition, as shown in FIG. 2, it can be manually raised, causing thespin clutch 28 to be raised above the inclined cam surfaces 20 a formedwithin the upwardly extending tubular extension 26. Such engagement ofthe clutch allows the spiral plunger to be raised to an upper mostposition to again repeat the cycle by again pressing the plungerdownwardly for continued rotation of the basket 18 by repeatedengagement and disengagement of the clutch from the central post 20.Dots or small protuberances 28 c (FIG. 2E) are spaced along the rim 28 athat minimize small points of contact with the under facing surface ofthe cap 32 when the clutch 28 is in a raised position to ensure that theclutch does not stick to the cap when the plunger is in an extendedposition but drops when the plunger moves vertically downwardly.

Preferably, an inner tube 36 is provided, as shown in FIGS. 2, 2B and 2Cthat extends from the inwardly extending tubular extension 24 to a pivotplug 34 that includes a disc portion 34 a, an inwardly-directed centraltubular extension 34 b, and central or axial downwardly-directed boss 34c. The boss 34 c is a downwardly projecting protuberance preferablyprovided with a generally rounded or pointed end as shown. The discportion 34 a is preferably adhered or otherwise affixed to the basket 18at the annular recess 22. A compression spring 38 is positioned axiallywithin the pivot plug central tubular extension 34 b and maintainedcentered by means of circumferentially spaced axial fins 34 d (FIG. 2K).The spring 38 engages the lower most end of the spiral plunger 27 whenit reaches its lowermost position to initiate an upward movement of theplunger. The elements or the components described in conjunction withFIG. 2 will be defined or denominated as a spin mechanism. The spinmechanism is generally similar to the spin mechanisms used in toyspinning tops and operates substantially in the same way.

Spinning the basket 18 on the boss 34 c within the jar 12 filled with afluid, aided by the radial fins 18 d, will create a degree of turbulencewithin the fluid especially if the basket is caused to rapidly rotaterelative to the fixed container jar 12, resulting in mechanical removalof debris and contaminants from items placed on the tray of the basket18.

Depending on the nature and properties of the fluids or cleaningsolutions used spinning of the carousel can also help to neutralize someor most contaminants. In a presently preferred embodiment of theinvention there is also provided a metal disc 42 with circular holes 42a (FIG. 2N) dimensioned and arranged to receive the circumferentiallyspaced projections 18 c on the basket 18 to rotate therewith.Preferably, the metal disc 42 is also provided with an array ofadditional distributed holes 42 b to increase its surface area.Selection of an appropriate cleaning fluid in conjunction with anappropriate metal disc 42 can be effective both at ambient temperatureor at an elevated temperature, with different degrees of advantage.Preferably, the container with the fluid is heated in a microwave ovento a temperature of at least 170° F. and preferably above 170° F. Thecleaning solution advantageously includes a relatively strong base, suchas sodium carbonate that dissolves and ionizes in water, acts as analkaline that disassociates into the weak carbonic acid and a strongeralkaline sodium hydroxide. The sodium carbonate solution provides theability to attack metals such as aluminum with the release of hydrogengas. The release of hydrogen gas provides a second or additionalmechanical mechanism for dislodging dirt and surface contaminants frommetal parts placed within the tray or basket 18. The sodium carbonate isalso useful as an electrolyte that acts as a good conductor in theprocess of electrolysis, creating carbonate ions that allows a smallelectrolytic current to flow. Hydrogen ions produced by this reactionreduce sulfide ions, for example, restoring silver metal. Disc 42,therefore, should be formed of a relatively active metal with increasedability to oxidize, such as aluminum, zinc, and nickel that can cleanreducing metals that have the ability of being reduced, such as silver,platinum and gold. The oxidation reaction, for example, drives thereduction of silver. In this case, aluminum is an oxidizing agentreducing silver sulfide to elemental silver while forming aluminumsulfide. A heated fluid or liquid, such as boiling water, with orwithout an ionizable salt, increases the reaction when the solutiontemperature is higher. Aluminum in pure water would not remove silvertarnish because there is a film of aluminum hydroxide that stops theoxidation reaction. Sodium bicarbonate removes the surface film ofaluminum hydroxide by dissolving it to expose fresh metallic aluminumready for oxidation. Dissolving the sodium bicarbonate also increasesthe ionic strength of the solution, which increases the rate of thereaction.

Referring to FIGS. 2J and 2K, details of the pivot plug 34 are shownincluding the disc portion 34 a and the tubular extension 34 b. Thecentral boss or protuberance 34 c extends in a direction opposite to thedirection of the tubular extension 34 b and is provided with a pointedor rounded end 34 c suitable for point contact to minimize friction whenspun or rotated on the bottom wall or central raised portion 12 h of thejar 12, when received and supported within the central depression 12 i.At least three spring centering fins or tabs 34 d are provided at theinner end of the tubular extension 34 b as shown.

Referring to FIG. 2I the spiral plunger 40 includes a flat upper end 40a and a flat bottom end 40 b, and an operative spiral portion 40 ctherebetween. A handle 40 d is fixed to the upper end 40 a andpreferably provided with a finger grip with insulating pads 40 e. Atransverse radial disc portion 40 f serves both to protect the user'shand from potentially hot cleaning fluids as well as for supportingopposed downwardly extending axial arms 40 g each of which includes aninwardly directed radial locking tab or finger 40 h. The arms 40 g andfingers 40 h are configured and dimensioned to be selectively receivablewithin diametrically opposite surface or exterior axial grooves 32 a inthe cap 32, when moved downwardly, and circumferential grooves 32 b,when rotated relative to the spin clutch cap 32 to provide abayonette-type connection to quickly and easily selectively lock thespiral plunger 27 to the central post or main body 20 or disengage ittherefrom (FIG. 3A). The disc portion 40 f is advantageously providedwith markings 40 i and 40 j (FIGS. 2I and 3A) that respectively indicateto a user the clockwise and counter-clockwise rotations of thefinger-grip 40 e to lock and unlock the plunger assembly 40 to or fromthe spinning mechanism or carousel 16.

Referring to FIGS. 2L and 2M a small part stabilizer 44 is shown that isgenerally disc shaped and dimensioned to be received within the tray ofthe basket 18. The stabilizer 44 includes a generally circular disc orplatform 44 a most of which is porous (e.g. mesh 44 b) and includessomewhat tapered axial projections 44 c dimensioned to frictionallyengage the central post 20 along different axial positions along thepost to accommodate jewelry or other small parts of different sizes bywedging the items to be cleaned between the disc or platform 44 a andthe tray of the basket 18. The axial projections 44 c may be somewhatflexible and inwardly inclined to expand when placed over the post infrictional engagement. Jewelry or small parts are placed on the tray ofthe basket 18 directly or on the metal 42 disc. The stabilizer 44 ismoved downwardly until there is contact between the stabilizer 44 a andthe items to be cleaned to prevent movements of the items to be cleanedwhen the basket 18 is rotated. The parts to be cleaned are maintainedfixed on the tray as it rotates and the fluids impinge against the itemsto be cleaned. This is enhanced by providing radial fins 44 d thatpromote agitation of the fluid.

Referring to FIG. 2O, a cleaning and resurfacing disc 54 may be used toresurface the disc 42, being provided with a finger grip 54 a and a disc54 b provided with an abrasive surface (not shown) on the disc 54 b.

The rinse bubble 46 and small parts stabilizer 44 are accessories thatwill be used as may be needed at user's discretion. This will depend onthe size and type of the jewelry being sanitized and rinsed. The linkwebsite of Jewelry Spa Hot Tub provides additional details, instructionsand examples to help a user decide what steps or accessories to choosefor a given task.

Referring to FIGS. 4A and 4B, a rinse bubble 46 is shown, preferablymade of transparent plastic. This is generally dome-shaped with acentral opening 46 a, dimensioned to receive central post or body 20, tocover the tray or base 18 a and any objects thereon to be cleaned. Alateral opening 46 b is provided dimensioned to receive a sink sprayerattachment to rinse off any chemical or cleaning solution residues onthe jewelry to be cleaned without splashing water beyond the rinsebubble.

Referring to FIGS. 5A and 5B a safety strainer 48 is shown dimensionedto be placed over and having a portion thereof 48 a fit within a drainof a sink. The circular strainer has a base formed of a meshed material48 b that allows the plunger mechanism to be removed from the jar 12 andsecurely positioned over the safety strainer with the rinse bubble inplace. This allows a jet of water to be sprayed through the lateralopening 46 b onto the parts to be cleaned and the water drained directlythrough the mesh 48 b at the bottom of the basket and through the safetystrainer without the danger of any jewelry or any small parts to bedislodged from the basket 18 and dropped and lost in the drain.

Referring to FIGS. 6A and 6B, a jewelry brush 52, made with SantopreneTPV rubber bristles 52 a, has many uses as with any brush except it willnot scratch shiny surfaces that are used in most all jewelry finishing.The tail or pick 52 b is designed to dig out dirt and grime that hasbeen softened by the cleaning device during the sanitizing step that hashardened and may need some help being removed. The construction of thehandle is polypropylene strong also safe to gems and the metals thatwill be sanitized.

FIG. 7 is an exploded view of the spinning mechanism or carousel 16 witha metal disc 42, a small part stabilizer 44, a rinse bubble 46 and aplunger assembly 40 positioned over the safety strainer 48.

Another feature of the invention is to form the outer shell 12 b of thejar 12 with a thermochromic material that will change the color of theouter shell in response to attaining a predetermined temperature. Thespecific thermochromic material used is not critical. However, it shouldbe selected to change light reflection, absorption and/or scatteringproperties at a predetermined temperature of a liquid heated in the jar12 placed in a microwave oven (e.g. at 1200 watts) so that the color ofthe outer shell 12 b can be a solid color, such as blue, when the liquidor cleaning solution is at ambient temperature, such as 72° F. After oneminute or two minutes, for example, when the temperature reachesapproximately 139° F. the outer shell 12 b starts to change colors to alight blue with some white regions and after 2-3 minutes when thetemperature of the cleaning fluid achieves sanitizing temperature of atleast 170° F. the outer surface of the outer shell 12 b turnssubstantially white over the entire visible area. This provides a visualindicator that the fluid or cleaning solution has reached its sanitizingtemperature and the container may be removed from the microwave oven andcan receive the carousel 16 with the basket 18 and the jewelry or itemsto be cleaned together with the plunger spinning mechanism for rotatingthe basket 18 within the heated cleaning fluid.

Referring to FIG. 8, a portable cleaning kit 50 in accordance with theinvention includes the following elements or components, some of whichmay be optional (as noted):

-   -   1. A container 10, including ajar 12 and a lid 14;    -   2. A spinning mechanism or carousel 16, including a basket 18;    -   3. a metal disc 42;    -   4. A small parts stabilizer 44;    -   5. A rinse bubble 46;    -   6. A safety strainer 48;    -   7. An optional combination brush and pick 52 (FIGS. 6A and 6B);    -   8.

The use and operation of the device will now be described.

-   -   1. The cleaning solution is prepared in accordance with        directions of the manufacturer. One solution suitable for use is        distributed by Jewelry Spa HOT TUB Inc., of Nyack, N.Y. under        the trademark “JEWELRY SPA”® and “HOT TUB”™.    -   2. Fill the jar 12 halfway to top with room temperature tap        water.    -   3. Add recommended amount of cleaning solution.    -   4. Top off with tap water to the maximum fill line 12 f.    -   5. Place sink safety strainer/caddy 48 over a kitchen sink drain        before attempting to use the container. This will allow only        water to drain and guard against any parts dropping into the        drain.    -   6. Place the lid counter or caddy 14, top side down, on a        kitchen counter next to the sink or other surface where the        device will be used.    -   7. Place the complete spin mechanism or carousel 16 on the lid        or on the counter caddy 14. The lid 14 doubles as a work station        drip tray for the carousel during operation. The four protruding        santoprene rests 14 b will grip and keep the basket from        spinning thereby allowing the handle 40 d to be easily removed        or reinstalled to prepare for the Sanitizing or Rinsing steps.    -   8. The spin handle is designed to be a one handed operation.        Remove the handle. With the handle off remove the rinse bubble        and small part stabilizer leaving the metal disc 42 in place.    -   9. Place the rinse bubble 46 and small part stabilizer 44 aside        as these will possibly be required during the rinsing step.    -   10. To remove the handle 40 d completely with the jar 12        positioned on the lid or counter caddy 14 to steady it, press        handle down then twist the handle counter clockwise (FIG. 9A) to        unlock. Then pull straight up and out of the central body or        post 20 (FIGS. 9B and 9C).    -   11. To reinstall the plunger 40 place the lower flat portion 40        b of the spiral shaft of the handle into the top of the central        body or post 20 and rotate until received through the        rectangular slot 30 and let the spiral shaft drop under its own        weight. It will drop spinning down into place. Twist counter        clockwise until the locking tabs line up and gently push down        (FIG. 9D) then twist clockwise to re-engage lock. The basket 18        can be maneuvered with one hand into or out of the jar 12 or        during the sanitizing or rinse operation etc.    -   12. Place the item or items to be cleaned and/or Sanitized into        the basket 18 lying them on the metal disc 42 (FIG. 9E). Larger        heavier items will steady themselves. However, with smaller        light weight jewelry like diamond studs, thin chains etc. small        part stabilizer 44 can be used at this time (See FIG. 9F). Or        both the small parts stabilizer 44 and the rinse bubble 46 can        be used for maximum security (FIG. 9G) This will keep the small        Jewelry steady while spinning the basket 18 as the items are        sanitized or rinsed.    -   13. Place handle back into the central body or post 20 and lock        into lifting position for rinsing, storage etc. (FIG. 9H). The        configuration of the device can be tailored for the individual        type of jewelry to be cleaned.    -   14. One item or multiple items can be sanitized according to the        types of Jewelry and what can fit in basket. In depth videos can        also be viewed at the website of Jewelry Spa Hot Tub.    -   15. The jar is placed into a microwave oven. The insulating        outer sleeve or shell 12 b turns white as sanitizing temperature        is reached. When sanitizing temperature is reached allow the jar        to sit for 30 to 60 seconds then carefully remove the jar and        place it on a kitchen counter or other surface where the user        will be working.        Heat up time results may vary. The following Table is based on a        fresh 12 oz. bath filled to the MAX fill line 12 f in the jar 12        at room temperature of 72° F. CAUTION should always be used when        heating and removing anything hot from a microwave oven. A safe        approach to avoid overheating is to start any of the recommended        heating time shown at 1.00 minute 30 seconds and increase in 30        second increments until a sanitizing temperature of 170° F. or        higher is reached. See below example color change chart.

-   -   16. The carousel 16 is now ready to be submerged into the jar        12.    -   17. Using one hand tilt the entire basket towards the side wall        of the jar (FIG. 9I). There are stops 12 m molded at the bottom        of the inner shell 12 a that help steady the basket 18 in order        to unlock the spin handle 40 d. Press down on the handle and        pivot to the left to release the spin handle.    -   18. Once released tilt the basket 18 back to the center along        the axis A_(c) of the jar 12 (FIG. 9J) and pull up handle (FIG.        9K) and then more forcefully push down (FIG. 9L) spinning the        basket slowly. Repeat for 30-60 seconds.        When pumping the handle up and down only move the handle halfway        so the locking tabs will not hit on the locking cap. The basket        can also be allowed to sit and soak for 30-60 seconds. Repeat        sanitizing step as necessary.    -   19. To setup for rinse, lock the spin handle 40 d in the lifting        position (FIG. 9M) and remove the dipping basket 18 out of the        jar 12. At this point there are two options for rinsing.        a) The dipping basket 18 can be placed back onto the lid or        counter caddy 14, (FIG. 9N) remove the handle completely, leave        the small part stabilizer in place (if used) (FIG. 9O) and place        the rinse bubble 46 back into position over the basket 18 (FIG.        9P), replace the handle and lock it in the lifting position then        place on the sink safety strainer for rinsing.        b) The carousel can be removed from the jar 12 and placed on the        sink safety strainer caddy 48 for Rinsing (FIG. 9T).    -   20. Place the carousel onto the sink safety strainer/caddy 48        positioned over the drain earlier. The carousel is designed to        sit securely on the strainer caddy. Turn on the faucet to apply        hot tap water (jewelry should always be rinsed using hot tap        water to avoid thermal shock to gemstones that are known to be        prone to this). Now using the sink sprayer position over or        directly into the lateral or side opening 46 b in the Rinse        Bubble 46 and spray the cleaned parts (FIG. 9S). If the sink is        not equipped with a sprayer the basket 18 can be held under the        faucet spout (FIG. 9Q). For larger jewelry it is not necessary        to use the small part stabilizer or the rinse bubble, the        jewelry should be heavy enough to stay in place while using        either rinsing procedure (FIG. 9R).    -   21. Place the dipping basket 18 back onto the lid and        counter/caddy 14 (FIG. 9T) and allow to cool as rinse water        drains. Excess water can also be removed by spinning the basket        while sitting on the lid or counter caddy 14 (FIG. 9U). Then the        rinse bubble, small part stabilizer can be removed, if used, and        finally the jewelry can be removed. The jewelry can be patted        dry with a paper towel. If some imbedded grime is still visible        the brush/pick 52 (FIG. 9V) can be used to assist, or the above        steps can be repeated.    -   22. The jewelry should always be cleaned in the container 10        before using the polishing cloth 58. Doing so will remove        contaminants that may be abrasive and will attach to the        polishing cloth. Bypassing the cleaning and rinsing steps will        result in scratching the highly polished surface of the jewelry        during polishing.    -   23. The polishing cloth 58 (e.g. the polishing cloth in the kit        supplied by Jewelry Spa HOT TUB Inc.) is laid down on a flat        surface (FIG. 9W), either side does not matter. Then with smooth        even strokes slide the jewelry back and forth. This will help in        brightening the high spots on the jewelry where it tends to        become dulled by wear.    -   24. Pick up the jewelry and wrap it in the cloth (FIG. 9X) to        get into some of the other areas that may need additional shine.        A paper towel can be used to finish wipe.

An approved Testing Laboratory with Good Lab Practices (GLP) tested thedevice and method and found that the cleaning device 10 is effective incleaning and/or sanitizing items of jewelry and removing the followingrepresentative test organisms: Staphylococcus aureus, Salmonellaspecies, Escherichia coli and Pseudomonas. Testing was performed byfilling the container 10 with approximately 3 oz of room temperature tapwater and adding half bottle (3 oz) of a suitable solution concentratethat can be heated in a microwave oven to a temperature in excess of170° F. Tap water was added to top off to tub fill line 12 f. Thecontainer 10 was then placed in a microwave oven. Initially, themicrowave oven was set to high for 1 minute 30 seconds and extended by30 second increments until the sanitizing temperature of 170° F. wasachieved. As a visual aid, the tub or container changed color from bluegreen to white once the proper temperature was reached. The temperaturewas verified with a thermometer. The heating times/microwave wattagechart was referred to as a guide. Once the proper time was determinedfor the microwave unit, the same time was used for all subsequent heatups. After sanitizing temperature was reached, the container or tub wasallowed to stabilize in the microwave for an additional 30-60 seconds toavoid potential splash over or spillage.

When exposing the inoculated jewelry to the system of high pH solutionand an average temperature of 177° F. for 30 seconds with mechanicalagitation, all bacteria present was removed by the process leaving thejewelry bacteria free based on the criteria present in the protocol.When exposing the inoculated jewelry to the system of high pH solutionand cold temperature of 76° F. for 30 seconds with mechanical agitation,all bacteria present was also removed by the process leaving the jewelrybacteria free based on the criteria present in the protocol.

On the basis of testing and observations it is clear that the device canbe used to clean jewelry and small parts by removing surfacecontaminants including oils and dirt, sanitizing the surfaces and/orboth. Oil, dirt and other surface debris/contaminants can be effectivelydislodged and removed by mechanical means including turbulence oragitation of the cleaning fluids in which the jewelry or other parts areimmersed and generation of chemical by-products such as generation ofgas bubbles in and around the metal disc 42 on which the parts aresupported. Heating of the cleaning fluids promotes the process byaccelerating chemical reaction release of gases as well as softeningsurface contaminants that may also harbor embedded pathogens when heatedas described the surfaces can also be effectively sanitized.
